辽宁省重点高中沈阳市郊联体2023-2024学年高二上学期期中考试英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Warrumbungle National ParkTravel six hours northwest of Sydney, and you’ve reached the astronomy capital of Australia. Warrumbungle National Park is a nature and star-lover’s dream. This land is home to the Southern Hemisphere’s first Dark Sky Park, which means you’ll be treated to nights of no light pollution and out of this world stargazing. Besides, the Warrumbungles has several adventurous hikes. The Breadknife and Grand High Tops walk is considered one of the best in Australia!Ku-Ring-Gai Chase National ParkKu-Ring-Gai Chase is the second oldest national park in Australia. We love this park for its proximity (邻近) to Sydney (a quick 45-minute drive from the city), significant Aboriginal (澳大利亚土著的) sites and breathtaking scenic views. There are many walks you can do here. You can also go kayaking (皮划艇), stopping at some of the secluded beaches that line the park.Bouddi National ParkLocated on the Central Coast, Bouddi National Park is one for beautiful landscapes and beaches. Just 90 minutes from Sydney, Bouddi is a hidden treasure. The beautiful water makes this park an ideal destination during summer, but it also provides a fantastic point for whale watching over the winter. You can experience Bouddi National Park on a day trip. Pack your picnic goods and head on the 8.5 km (one-way) Bouddi Coastal Walk — it’ll give you a perfect taste of the best of what the park has to offer!Dorrigo National ParkAs a UNESCO World Heritage Site, Dorrigo National Park is one to explore! Located just shy of four hours from Byron Bay, the park is part of the Gondwana Rainforests and has been made over millions of years. You’d be right then to expect some of the most stunning waterfalls here. For one of the best experiences, head to the Skywalk lookout. This elevated walkway will take you right into the heart of the rainforest, providing soaring views 21 meters over the rainforest all the way to the coast.1．If you were a fan of stargazing and hiking, which park would interest you most?A．Bouddi National Park.B．Dorrigo National Park.C．Warrumbungle National Park.D．Ku-Ring-Gai Chase National Park. 2．What can you enjoy at Bouddi National Park?A．Going kayaking.B．Watching whales.C．Visiting Aboriginal sites.D．Seeing breathtaking waterfalls. 3．What do you know about Dorrigo National Park?A．It is the oldest national park in Australia.B．It offers a perfect view of the Gondwana Rainforests.C．It’s about four hours drive from Sydney.D．It’s known for adventurous hikes along the coast.I can’t miss the little old lady with her kerchief (方头巾) on her head, a black umbrella blowing all over. I can tell she is freezing. She is standing at a bus stop, and I’m driving by, late for my early morning shift. I decide to stop and offer her a ride.Of course, she declines, but when I ask again and insist, finally, she gets in the car. I take her to her destination, and by the time she gets out of my car, she is smiling and thanks me.I was late for work that day, but I was so glad that I stopped. That was 40 years ago, and the beginning of a new habit, one that continues when I’m out driving in bad weather.If there’s someone at a bus stop, especially if it’s an elderly person waiting at off hours and in bad weather, I will pull over and ask if they need a ride.Once, a young doctor jumped in. She had finished a long shift and had been waiting and waiting at the bus stop. She had no hesitation and, for the first time, I was able to help someone who performs miracles (奇迹) on a daily basis. That felt good.But the best part of my ride offers is the conversation. I do tend to ask a lot of questions: where are you from, where are you going, family, background, pets and whatever else comes to mind. Surprisingly, everyone wants to chat. We are usually laughing by the time the ride is over. “What a shame!” I often think when they hop out, as the stories were just getting started.Now as retirement approaches, I believe I have found my calling. I will be happy to join a community driving program to take people to one appointment or another — or perhaps just to the coffee shop to sit and listen for an hour.As the years pass, perhaps I will be the one standing at the bus stop. Perhaps there will be somebody who rolls down a window and offers me a seat for a little ride. I will continue to take that leap of faith in the kindness of strangers.4．What are the first three paragraphs mainly about?A．How the author started offering rides.B．The value of the author’s actions.C．An old lady who impressed the author.D．An accident that happened 40 years ago.5．What does the author like most about her ride offers?A．Helping people who contribute to society.B．People accepting her offer without hesitation.C．Chatting with her passengers.D．Making friends with her passengers.6．What does the author plan to do?A．Become a taxi driver after retirement.B．Continue driving people to their destinations.C．Wait to be offered a ride at a bus stop.D．Share her stories with more people.7．What message does the author want to convey?A．Elderly people need more care and support.B．It is important to find a purpose in life.C．Offering rides to strangers involves risks.D．Always believe in the goodness in people.People’s first memories are all autobiographical (自传式的), or memories of significant experiences in their lives, and these events typically didn’t happen before the age of 2 or 3. In fact, most people can’t remember things from the first few years of their lives—a phenomenon researchers have called infantile amnesia.However, research suggests that infants (婴儿) can form other kinds of memories. Within the first few days of life, infants can recall their own mother’s face and distinguish it from the face of a stranger. A few months later, infants can demonstrate that they remember lots of familiar faces by smiling most at the ones they see most often.But if so, why do people experience infantile amnesia? Though it still isn’t clear whether it’s because we can’t form autobiographical memories, or whether we just have no way to retrieve (找回) them, scientists have a few guesses.One is that autobiographical memories require you to have some sense of self. Researchers have tested this ability using a mirror recognition task called the rouge test. It involves marking a baby’s nose with a spot of red lipstick.Researchers then place the infant in front of a mirror. Infants younger than 18 months just smile at the baby in the reflection, not showing any evidence of recognizing themselves or the red mark on their face. Between 18 and 24 months, infants touch their own nose, even looking embarrassed, suggesting that they connect the red dot in the mirror with their own face—they start to form some sense of self.Another possible explanation is that because infants don’t have language until later in the second year of life, they can’t form narratives about their own lives that they can later recall. Finally, the hippocampus (海马体), which is the region of the brain that’s largely responsible for memory, isn’t fully developed in the infancy period.Scientists will continue to investigate how these factors may contribute to infantile amnesia.8．What can infants do in their first few months?A．Memorize most of their family members.B．Distinguish between familiar and unfamiliar faces.C．Remember a string of events from the recent past.D．Identify their own reflections in the mirror.9．What do infants tend to do after 18 months, according to the rouge test?A．See their reflections as themselves.B．Ignore the marks on their faces.C．Enjoy playing with their reflections.D．Show a strong interest in the mirror.10．What could be a cause of infantile amnesia, according to the text?A．Infants’ inability to recall memories.B．Infants’ immature hippocampus.C．Infants’ undeveloped communication skills.D．Infants’ unsteady autobiographical memories.11．Which of the following can be the best title for the text?A．When do babies start remembering things?B．Why is it hard to retrieve lost memories?C．How do kids form their first memories?D．Why can’t we remember being a baby?Three years after “eating” a star, a black hole has been seen “vomiting (呕吐)”.According to a paper published in October in the Astrophysical Journal, scientists from Harvard University claimed that in 2018, a small star was torn to dust and swallowed by a black hole named A T2018hyz in a galaxy (星系) 665 million light-years away from Earth.Then, the same black hole becomes active again. However, it hasn’t swallowed anything new; it has been seen ejecting (喷射) material at half the speed of light.“This caught us completely by surprise — no one has ever seen anything like this before,” said Yvette Cendes, astronomer and the leading author of the new study, in a press release in the US.Black holes use their gravitational pull (引力) to draw matter into a small space with a force so strong that not even light can escape. They are usually formed by the collapsing pieces of large dying stars and can consume anything that comes too close.When a black hole swallows a star, some pieces may be thrown back into space – astronomers tend to call black holes messy eaters, according to the US Center for Astrophysics. The whole event is called a tidal disruption event (TDE).However, a TDE usually happens immediately after the swallow, not three years later as was the case with black hole AT2018hyz. Cendes posted on social media that the event was like “burping” after a meal.The team made assumptions about the possible reasons behind the event. According to their paper, scientists first turned to the density theory. If the density is very high around the black hole, the matter might be drawn out, causing an ejection. Another thought was that the other TDEs were in directions that could not be observed from Earth. However, scientists have yet to determine the true reason.“The next step is to explore whether this actually happens more regularly and we have simply not been looking at TDEs late enough in their evolution,” Edo Berger, co-author of the study, told the Harvard Gazette.12．What does the underlined word “this” in paragraph 4 refer to?A．A black hole ejected something new.B．A black hole swallowed a faraway star.C．A black hole vomited years after eating.D．A dead black hole became active again. 13．What do we know about black holes?A．They are unable to consume light.B．They take up a large amount of space.C．They are a mix of countless dying stars.D．They result from the collapse of large stars.14．What does the second-to-last paragraph mainly talk about?A．Supporting evidence for the research result.B．Potential applications of thescientific finding.C．Reasonable doubts about the research process.D．Possible explanations of the scientific discovery.15．Which aspect of TDEs will scientists plan to research?A．Their origins.B．Their effects.C．Their frequency.D．Their development.二、七选五Mindfulness(正念) is defined as turning your attention inward and being aware of yourhelp lower stress, reduce anxiety, increase a person’s ability to enjoy positive experiences, and more. Here are a few ways to practice mindfulness.Listen to music17 . Getting lost in a good song is an effective way to practice mindfulness. Before listening to your favorite album, consider what you’re focusing your attention on. That way, you’ll be able to tell if your mind starts to wander.Walk your dogSay you’re heading outside with your pet. Instead of thinking about the workday ahead, stay focused on the present. Notice your dog’s tail wagging(摆动) and the sounds of his breath. 18 .Focus on your movementsAs you walk into the office in the morning, focus only on your movements. 19and repeat the words “ lifting, moving, placing, shifting”. Doing so will help avoid unwelcome worries.Feel the natureResearch suggests that spending even a little time in nature promotes happiness and attentiveness. If you want to get mindful in nature, head to a park for a walk or run. 20 . If you choose sight, for example, ask yourself: What are you seeing and what colors are noticeable?A．Pick one sense to focus onB．A mindfulness practice can benefit you a lotC．Sound can give you energy, calmness, or bothD．A person can practice mindfulness in any activityE．Our minds tend to focus on worries about the futureF．Pay special attention to your feet as they touch the groundG．Any time your mind wanders, quickly bring your attention back to your pet三、完形填空23．A．leave B．search C．work D．hide 24．A．intelligent B．unsuspecting C．aggressive D．cautious 25．A．reach B．step C．look D．feel 26．A．give B．knock C．pull D．throw 27．A．save B．protect C．distract D．stop 28．A．locked B．involved C．stuck D．hurt 29．A．head B．hand C．leg D．tail 30．A．releasing B．tasting C．touching D．moving 31．A．trying B．forgetting C．refusing D．expecting 32．A．feed B．free C．help D．catch 33．A．warned B．ordered C．whispered D．sighed 34．A．return B．start C．change D．quit 35．A．calling B．taking C．holding D．pushing四、用单词的适当形式完成短文阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
